JOHN It. JONES, OF OLARKSVILLE, IOWA.

-- EARTH-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 250,545, dated December6, 1881.

Application filed August 31, 1881.

To all whom it may concern:

Be it known that I, JOHN R. JONES, of Olarksville,in the county ofButler and State of Iowa, have invented a new and useful Improvement inEarth-Scrapers; and I do hereby declare that the following is a full,clear, and exact description of the same.

My invention relates to road or earth scrapers. The principal object ofthe invention is to overcome or avoid the leverage in recovering thescraper after it has been overturned in dumping the load.

My invention consists, first, of an intermediate link pivoted to thescraper on each side, near the front or edge, and also pivoted to thebail or to a chain which may be used in place of the bail.

It consists, in the second place, of a fiattened or elongatedsocket-piece in combina tion with the intermediate link on each side,said socket-pieces being bolted to the sides and having the linkspivoted therein, whereby the movement of said links is limited, all ashereinafter fully explained.

In the accompanying drawings, Figure 1 represents a side elevation ofthe scraper with my improvements attached, the scraper resting upon itsbottom,asin carrying a load. Fig. 2 shows the scraper in the act ofbeing tilted, resting in an inclined position upon the ends of thelinks. Fig. 3 represents the same form of scraper in position,as shownin Fig.1, with a chain attached, instead of a bail. Fig. 4 shows a sideelevation of scraper upset.

. The body of the scraper A is of ordinary construction and providedwith the ordinary handles, a a. On each side, near the forward end, arefixed socket-pieces b 1), adapted to receive the ends of the links 0 0.These socketpieces may be made of cast or wrought iron, in anywell-known way. If made of cast-iron, they maybe formed with a completepocket or recess, in which the ends of the links are received andpivoted or they may be made of a plate of sheet metal struck up intoproper shape and bolted to the sides of the scraper, which, in thatcase, forms one side of the recess or pocket in which the link works.lprefer to form this piece with a rear extension, 1, for more convenientand secure attachment to the scraper. The form of the socket is shown infigures. The link is pivoted in the angle of the two sides or ends ofthe socket, so that it (No model.)

may swing on its pivotal bolt through an arc of ninety degrees or less.The lower edge of the socket is approximately horizontal, to allow thelink to assume proper position in action. The forward ends of thelinksare pronged, as shown in the figures, and the ends of the bail arepivoted between these prongs. One prong of each link is prolonged andpointed, as shown at 2.

Instead of an ordinary bail, I may use with this device an ordinarychain, the ends of the chain being hooked or otherwise secured to thepronged ends of the links.

The action of the improved scraper is shown in Figs. 1,2, and 4. Whenthe draft is stopped and the scraper lifted for dumping, the points ofthe links 0 will enter the ground, causing the scraper to swing backwardon the pivot, assuming the position shown in Fig. 2; and when thescraper is turned completely over, as in Fig. 4, the prongs extendbackward, forming a pivot, upon which the scraper is turned to bring itinto upright position again. The lower end of the socket, (forconvenience of reference marked 3,) by reason of being approximatelyparallel with the bottom of the scraper, causes the links, when thescraper is raised a ter being dumped, to stand also parallel with thesame plane, by means of which the scraper turns on the points 2 until itpasses the perpendicular line, when the links turn in the sockets andare limited by the other end of the triangular socket, (marked 4.)

Having thus described my invention, what I claim is- 1. The combinationof the scraper, the bail or chain, and the intermediate links, the Wholebeing constructed and operating as set forth.

2. The combination of the scraper, the socket-pieces, the intermediatelinks, and the bail or chain, as described.

3. The combination of the scraper, the links pivoted thereon, andprovided with points projecting beyond the place where the ends of thebail are pivoted, all as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN R. JONES.
